Product Overview
A bow limb is an energy-storage spring that must survive millions of bend cycles within millimeters of its failure envelope — precisely the discipline where carbon’s stiffness-to-weight and fatigue behavior beat wood and fiberglass. T300-class standard-modulus fiber in pultruded flat strip is the starting material most limb builders use, ground after curing into the working tapers that set draw weight and force curve. An honest specification note belongs here: the strip alone does not make a limb. Limb performance comes from the laminate design — strip thickness profile, glass or carbon facings for torsion control, and the full stack’s glue lines — and pultruded UD strips contribute axial stiffness and fatigue life to that system. Lot discipline matters: fiber alignment drift or void content shows up months later as limb failure at full draw, so straightness and ultrasonic/void inspection per lot are worth specifying explicitly. Manufacturers listed here supply raw strips, CNC-ground tapered profiles to limb drawings, and volume programs for archery OEMs.
