Wonder if a lock and chain would be sufficent.Originally posted by l3stat:BINGO! hey if this is successful, i'll share the method with everyone, as well as where to buy it.. provided i can find it... then we can have peace of mind when we leave our helmets locked on the bike. but one thing is that i've to check if kevlar burns... -

pls pls pls dont mind, my post will sound negative, but its a little opinion from me dats all.
are you attempting to replace the velcro strap of helmets wif kevlar? and is the sole purpose to prevent theft by preventing ppl from stealing helmet thru cutting the strap when you lock at the bike's helmet lock?
my opinion is, kevlar is way too expensive for such a use. obviously kevlar straps unlikely to improve safety coz the strap doesnt cover much of your head. all i wanna say is, such a venture does not make much economic sense. of coz, it is a worthwhile project for a biker if he happens to come by some spare kevlar strips. but kevlar is just so hard to come by.
hope nobody offended, just felt the venture does not make much economic sense, although without u doing the project yet i am already sure a helmet wif kevlar strap will indeed be difficult to cut and steal.

den something dat u cant cut thru u haf to sew or stitch onto the helmet, and the stitch will be the weakest link.
but no harm trying on one to see if it works. -
i'm sourcing for the cheapest kevlar i can find, hopefully with quantity, with the support of everyone, we can enjoy the benefits at a cheaper cost. the main point of the strap is not to protect our chins; kevlar is a soft fabric, while it has high strength, it is not rigid. if you buang with your chin covered with kevlar, you will not be cut, guaranteed, but your jaw will be out of shape.
as for sewing, the stitches still can be cut off. i just got an email from a professor in NTU who has done research on kevlar. he said that proper adhesives (which he did not elaborate which), can successfully bind kevlar to form an impermeable, strong structure. the idea would be to glue the strap to the helmet, and glue the end to contain the D-rings.
lastly, kevlar is fire-proof. other than using industrial strength bolt cutters to cut your helmet lock, i dunno how the ah-beng can stun your helmet liao.
if it costs $10 or so (hopefully, i'm still trying to source for the material), why not when it can save you many many $40s for helmets?
by the way i'm not taking any of your replies negatively, just hope to convince you guys that IF it can be done at a reasonable cost, everyone stands to benefit!

Cool idea..Although i dont see any economic sense, but i must give credit to you..At least someone have a good idea and brave enough to venture..
Maybe instead of you kelvar, you might one to research on some other materials that is as tough and as durable as kelvar?? Maybe less tough but if its easy to produce and find and its good enough to prevent ah beng from stealing helmet...by all means!!!!
Just a thought!!!

so now "economic sense" is the buzzword eh?? would you spend half the money you'd use to buy a new helmet, so that you'll save the cost of 3 others? i don't see how hard it is to see the "economic sense" behind it.Originally posted by shah_1708:Cool idea..Although i dont see any economic sense

I think u can cut kevlar with sissors wan leh. im not too sure after all it is juz something like a fabric.

nope, you cant.Originally posted by fp2075r:I think u can cut kevlar with sissors wan leh. im not too sure after all it is juz something like a fabric.
if i'm not wrong (if i am and someone knows better welcome to correct me), its true that kevlar is basically made of fabric, but it is highly densitive woven fabric. as such, cutting thru a thin piece of kevlar is the same as cutting, for example, a shirt that is hundreds of pieces of cloth thick.
it all depends on how dense the kevlar is. at its most dense, it is hard, and that is used to make the army helmets, that no longer feels like fabric but rather like solid. the bulletproof vest is less dense, hence feels like very thick shirt. and the racing suits are less dense, to make it more flexible, and anyway heh heh dont tear when buang can already in gp nobody shoot pistol at u!
anyway, no you cant find kevlar at army surplus shops in beach road. kevlar is supplied straight to industries requiring their use. hence u need one good lobang at industries using them. best bet is places like S'pore Technologies labs as sakaratulz mentioned.

can try asking army guys that rod....
too bad i still need my helmet for army reservist.....or else i can dontate my kevlar helmet, but i dunno how u going make strips out of that...hahaha -
maybe if it's thin, it'll be possible but very hard. your scissors must be super sharp. but like ducati has said, it is very tough. looks and feels like silk, but very very tough. saw a video presentation during one of my sch lessons, a guy was wearing gloves made completely of kevlar. he used his gloved hand to grip a knife... slide here slide there but nothing happened. no cuts etc...Originally posted by fp2075r:I think u can cut kevlar with sissors wan leh. im not too sure after all it is juz something like a fabric.

dats wat i mentioned before. the helmet that kevlar is too dense. wats needed is a less dense kevlar, in my opinion best is the kind used to make the racing suits. i think even bulletproof vest is too dense.Originally posted by notti:can try asking army guys that rod....

but then, where to find racing suit ppl throw away? and oso, heh heh, if can find, HOW U CUT INTO STRIPS? heh heh very good question dont u think?
